Bedellia silvicolella mines

Convolvulus floridus, Teneriffa; from Klimesch (1979a)

mine

Oviposition at the leaf lower surface, near a vein. At first a slender gallery is made, with a thick, central frass line that sometimes occupies the entire width. After the first moult the larva makes gradually larger, brownish, full depth fleck mines, often in different leaves. The entrance to the mines always is at the lower surface. During movements, and before entering into a leaf a loose web is made, where frass grains use to be trapped.
